Navigation Problems USCG Question #1602 (Set 48)

You are on a voyage via position LAT 44°00'N, LONG 150°00'E to LAT 46°15'N, LONG 124°00'W. Using gnomonic chart WOXZC 5270, determine which statement is TRUE?

Official USCG Answer & Rule Citation

Correct Answer: Option B — A composite sailing with a limiting latitude of 51°N will clear the Aleutian Islands.

Bowditch principles for composite sailing dictate that a limiting latitude is chosen to keep the vessel away from high-latitude hazards. By setting a limiting latitude of 51°N, the great circle track is constrained, effectively allowing the vessel to clear the Aleutian Islands while maintaining an efficient route across the Pacific.
